Refactoring of connection setup and happy eyeballing. Move
nghttp2. ngtcp2, quiche and msh3 into connection filters.
- eyeballing cfilter that uses sub-filters for performing parallel connects
- socket cfilter for all transport types, including QUIC
- QUIC implementations in cfilter, can now participate in eyeballing
- connection setup is more dynamic in order to adapt to what filter did
really connect. Relevant to see if a SSL filter needs to be added or
if SSL has already been provided
- HTTP/3 test cases similar to HTTP/2
- multiuse of parallel transfers for HTTP/3, tested for ngtcp2 and quiche
- Fix for data attach/detach in VTLS filters that could lead to crashes
during parallel transfers.
- Eliminating setup() methods in cfilters, no longer needed.
- Improving Curl_conn_is_alive() to replace Curl_connalive() and
integrated ssl alive checks into cfilter.
- Adding CF_CNTRL_CONN_INFO_UPDATE to tell filters to update
connection into and persist it at the easy handle.
- Several more cfilter related cleanups and moves:
- stream_weigth and dependency info is now wrapped in struct
Curl_data_priority
- Curl_data_priority members depend is available in HTTP2|HTTP3
- Curl_data_priority members depend on NGHTTP2 support
- handling init/reset/cleanup of priority part of url.c
- data->state.priority same struct, but shallow copy for compares only
- PROTOPT_STREAM has been removed
- Curl_conn_is_mulitplex() now available to check on capability
- Adding query method to connection filters.
- ngtcp2+quiche: implementing query for max concurrent transfers.
- Adding is_alive and keep_alive cfilter methods. Adding DATA_SETUP event.
- setting keepalive timestamp on connect
- DATA_SETUP is called after the connection has been completely
setup (but may not connected yet) to allow filters to initialize
data members they use.
- there is no socket to be had with msh3, it is unclear how select
shall work
- manual test via "curl --http3 https://curl.se" fail with "empty
reply from server".
- Various socket/conn related cleanups:
- Curl_socket is now Curl_socket_open and in cf-socket.c
- Curl_closesocket is now Curl_socket_close and in cf-socket.c
- Curl_ssl_use has been replaced with Cur_conn_is_ssl
- Curl_conn_tcp_accepted_set has been split into
Curl_conn_tcp_listen_set and Curl_conn_tcp_accepted_set
with a clearer purpose
Closes#10141
- reverse order of haproxy and final ssl cfilter
- make haproxy avaiable on PROXY builds, independent of HTTP support as
it can be used with any protocol.

Fixes#10165Closes#10167
- `Curl_ssl_get_config()` now returns the first config if no SSL proxy
filter is active
- socket filter starts connection only on first invocation of its
connect method
Fixes#9982Closes#9983
This makes a big difference for cases when the rewind is not actually
necessary to perofm (for example HTTP response code 301 converts to GET)
and therefore the rewind can be avoided. In particular for situations
when that rewind fails, for example when reading from a pipe or similar.

Fixes#9735Closes#9958
- almost all backend calls pass the Curl_cfilter intance instead of
connectdata+sockindex
- ssl_connect_data is remove from struct connectdata and made internal
to vtls
- ssl_connect_data is allocated in the added filter, kept at cf->ctx
- added function to let a ssl filter access its ssl_primary_config and
ssl_config_data this selects the propert subfields in conn and data,
for filters added as plain or proxy
- adjusted all backends to use the changed api
- adjusted all backends to access config data via the exposed
functions, no longer using conn or data directly
cfilter renames for clear purpose:
- methods `Curl_conn_*(data, conn, sockindex)` work on the complete
filter chain at `sockindex` and connection `conn`.
- methods `Curl_cf_*(cf, ...)` work on a specific Curl_cfilter
instance.
- methods `Curl_conn_cf()` work on/with filter instances at a
connection.
- rebased and resolved some naming conflicts
- hostname validation (und session lookup) on SECONDARY use the same
name as on FIRST (again).
new debug macros and removing connectdata from function signatures where not
needed.
adapting schannel for new Curl_read_plain paramter.
Closes#9919
- Adding Curl_conn_is_ip_connected() to check if network connectivity
has been reached
- having ftp wait for network connectivity before proceeding with

Closes#9952
- general construct/destroy in connectdata
- default implementations of callback functions
- connect: cfilters for connect and accept
- socks: cfilter for socks proxying
- http_proxy: cfilter for http proxy tunneling
- vtls: cfilters for primary and proxy ssl
- change in general handling of data/conn
- Curl_cfilter_setup() sets up filter chain based on data settings,
if none are installed by the protocol handler setup
- Curl_cfilter_connect() boot straps filters into `connected` status,
used by handlers and multi to reach further stages
- Curl_cfilter_is_connected() to check if a conn is connected,
e.g. all filters have done their work
- Curl_cfilter_get_select_socks() gets the sockets and READ/WRITE
indicators for multi select to work
- Curl_cfilter_data_pending() asks filters if the have incoming
data pending for recv
- Curl_cfilter_recv()/Curl_cfilter_send are the general callbacks
installed in conn->recv/conn->send for io handling
- Curl_cfilter_attach_data()/Curl_cfilter_detach_data() inform filters
and addition/removal of a `data` from their connection
- adding vtl functions to prevent use of Curl_ssl globals directly
in other parts of the code.

Commit b5a434f7f0 inhibits the warning
on implicit fallthrough cases, since the current coding of indicating
fallthrough with comments is falling out of fashion with new compilers.
This attempts to make the issue smaller by rewriting fallthroughs to no
longer fallthrough, via either breaking the cases or turning switch
statements into if statements.
lib/content_encoding.c: the fallthrough codepath is simply copied
into the case as it's a single line.
lib/http_ntlm.c: the fallthrough case skips a state in the state-
machine and fast-forwards to NTLMSTATE_LAST. Do this before the
switch statement instead to set up the states that we actually
want.
lib/http_proxy.c: the fallthrough is just falling into exiting the
switch statement which can be done easily enough in the case.
lib/mime.c: switch statement rewritten as if statement.
lib/pop3.c: the fallthrough case skips to the next state in the
statemachine, do this explicitly instead.
lib/urlapi.c: switch statement rewritten as if statement.
lib/vssh/wolfssh.c: the fallthrough cases fast-forwards the state
machine, do this by running another iteration of the switch
statement instead.
lib/vtls/gtls.c: switch statement rewritten as if statement.
lib/vtls/nss.c: the fallthrough codepath is simply copied into the
case as it's a single line. Also twiddle a comment to not be
inside a non-brace if statement.
